It has been established that the absolute number of unique protein coding sequences does not correlate with organismal complexity.Which characteristic would not be consistent with this observation?
A) There are proportionally more transcription factors in humans than in nematodes.
B) The noncoding portion of the human genome is proportionally larger than in nematodes.
C) There are more alternative splicing variants in the human brain than in a chimpanzee brain.
D) More miRNA sequences have been identified in humans than in fruit flies.
E) There are fewer siRNA regulatory sequences in petunias than in mosses.

The observation that the absolute number of unique protein-coding sequences does not correlate with organismal complexity suggests that complexity may arise from regulatory mechanisms rather than the sheer number of genes. Choices A, B, C, and D all describe scenarios where regulatory complexity could account for organismal complexity without requiring a greater number of unique protein-coding genes. Choice E, suggesting fewer siRNA regulatory sequences in a more complex organism (petunias) compared to a less complex one (mosses), does not align with the idea that regulatory complexity contributes to organismal complexity.
